DRAIN-coax.

Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed. July 13, 1917. Serial No. 180,273.

To all-whom it may concern Be it known that I, JAMES B. KIRBY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga' and State of Ohio, have invented a certain new.

the provision of a device of this character of great cheapness, simplicity, reliability, lightness, facility of operation and non-corrodibility. Other objects and advantages will appear as the description proceeds.

. In the drawings accompanying and formin tr ted the preferred embodiment ofmy invention, although it will be understood that the same constitutes only one of a great number of mechanical forms in which the same may be embodied; and have shown the same operatively connected to a part of a washing machine, although it will be understood that this constitutes only one of a great number of possible uses and that I do not limit myself to use in this position or relation. In these drawings Figure 1 represents a perspective view of my improved draw-off cock separate from the container with which it is used; Fig. 2 illustrates the samecock in longitudinal section in position on a washing machine, the line of section being indicated at 2-2 on Fig. 3; Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 2; Fig. 4 is a perspective view of the movable member of my improved cock, 9. portion of the flange being broken away; and Fig. 5 represents a longitudinal sectional view through a modified form of cook, the valve member being in open position.

Describing the parts by reference characters,-m improved cock comprises a cylindrical b0 y 1 terminating at one end in the attaching snout 2 .and having at one side a radial spout 3' which is offset longitudinally from said snout. In the form shown in Figs. 1 to 4 inclusive the end of'the snout is a part of this application I have illusupturned and is surrounded by an attaching flange 4 by which the device may be secured to the bottom of a receptacle in any suitable manner as by rivets 5; and in the present embodiment this flange lies in a plane which is substantially tangent to one side of the casing 1, although it. is obvious that this is a mere matter of design. The side of the casing adjacent to this flange is also shown as provided with an apertured ear 6 adapted to be secured to the side of the receptacle for greater security as shown in Figs. 2 and 3.

In the form shown in Fig. 5, the snout is axial with the body and is slightly tapered so as to be driven into a wooden receptacle.

Of course threads. flan es, and other connecting expedients can be employed, if desired, without departing from my invention;

The interior of the casing 1 is reamed out to form a substantially cylindrical bore 10 in which is mounted the movable member of the valve or cock, which consists of a hollow cup shaped member having cylindrical walls 11. a transverse closing-end 12. and a flaring lip 13. the latter being preferably rolled completely over upon itself and corrugated as shown at 14 for greater ease of manipulation. The side wall 11 of the valve member is formed with a bayonet slot. which consists of a longitudinal part 15 merging with a transverse part 16. In the present embodiment this slot is cut clear throughthe wall 11, which is thin. but this is not essential to the invention. The bore 10 terminates in a flat transverse seat 20 arranged between the spout 3 and snout 2. and'the end of the valve member is provided with a packing ring or gasket 21-secured in place in any suitable manner as by the washer 22 and rivet 23. The side wall of the casing. 1 is provided with a pin-24 pro" jecting radially inward and engaging the slots 15, 16. the position of this pin being such that when in enga ement with the slot 16 the gasket 21 will be in contact with the seat 20 and the valve will be closed. In order to open the valve it is necessary merely that the movable member be rotated through a small. angle and then drawn longitudinally while the opposite movement serves to close I the same.

The pin 24 may either be threaded into the side of the casing as shown in Figs. 2 and 3 or merely driven therein as shown in Fig. 5. The movable member of the valve is preferably made of thin sheet brass drawn to the desu'ed shape, since from its simplicity and regularity it can easily be made on a punch press. The entire casmg can be used exactly as it come; from,

the casting mol'ds excepting for the reaming of the bore 10 and the drilling of the hole for the pin, although the spout is sometimes threaded as shown and the flange 4 is sometimes faced. However, the simplicity and thinness of the device makes it very light so that it can be made of brass without extravagance, and if made of cheaper materials like cast iron it can profitably be vgalvanized or otherwise rust-proofed since there are no screw threads, packing glands or other working surfaces whose fit and smoothness would be impaired by such an operation. g 1

It will be understood that many changes in detail can be made within the scope of my invention and I desire that the claims hereto annexed shall be read with this. intent in view.

Having thus described my invention, what I claim is 1. In a device of the character described,

a casing having a cylindrical bore, a seat and the outer end being formed with an inv gral corrugated li whereby it may be grasped, and inter tting means carried by said member and casing whereby the former may be held againstsaid seat.

2. A valve member for a draw-01f cook consisting of a hollow sheet metal cup of substantially cylindrical shape having .a bayonet slot in its wall and an enlarged corrugated lip integral therewith.

In testimony whereof I hereunto affix my signature.

JAMES B. KIRBY.
